I would recommend nothing short of this company. HID's, this is what they do, day in and day out, nothing else. Me personally, I use companies that specialize on one thing so I know they are focused on what I need. Tons of cool stuff on the website for complete retrofits to kits. My profession has me working with this type of lamp system on a much larger scale (upwards of 15000 watts) so I understand the entire premise behind it. Components are key here if you want to do it right, and for automotive aftermarket I have found nobody that does it as well as these guys. Either way read about Morimoto on google, you'll see the reviews are tops and they come with a 5 year warranty to boot.....
